Small NAF slewing ring bearings are generally composed of worm rods, slewing bearings, casings, motors, and other components. Because the key components use slewing bearings, they can bear radial force, axial force, and overturning moment. There are many ways, but this structure is based on its advantages. The following editor will take a look at the structure of small slewing ring bearings with you.
According to different structural methods, small slewing bearings can be divided into several types of contact ball turret bearings, alternating cylindrical (tapered) roller bearing turret bearings, single-row and double-row four-point ball turret bearings, double-row spherical turret bearings, ball bearings Combined bearings and turntable bearings composed of three-row cylindrical roller bearings and other structural methods. All kinds of rolling bearings can be divided into different structures such as toothless type, external tooth type, or internal tooth type according to whether they have teeth. The transmission gear position can be divided into toothless type, external tooth type or internal tooth type, etc.
According to different structural characteristics, small slewing bearings can meet the requirements of servers under various load specifications. Among them, the multi-point contact ball turret bearing has a higher dynamic load capacity, and the alternating cylindrical roller bearing turret bearing has a higher static load capacity. The three-row cylindrical roller bearing constitutes the turntable bearing. Due to the improvement of the bearing capacity, the length-to-diameter ratio of the rolling bearing is increased, and various loads are freely borne by the dovetail guide rail and the roller bearing group under the same support specification. The straight rail of its dovetail guide rail is much smaller, and it makes the server more compact, which is the turntable bearing with high load capacity.
